Ecological And Erosion Protection Functions Of Chesapeake Bay Living Shorelines : Comprehensive Monitoring Of Ecological And Erosion Protection Functions Of Chesapeake Bay Living Shorelines (Cmls), Phase I, Donna Marie Bilkovic, Molly Mitchell Dec 2011

Ecological And Erosion Protection Functions Of Chesapeake Bay Living Shorelines : Comprehensive Monitoring Of Ecological And Erosion Protection Functions Of Chesapeake Bay Living Shorelines (Cmls), Phase I, Donna Marie Bilkovic, Molly Mitchell

Reports

Armoring shorelines to prevent erosion, improve access, and accommodate individual landscaping interests can result in fragmentation or loss of habitats, reduction in capacity to moderate pollutant loads delivered to coastal waters, reduction in nekton and macrobenthic integrity (Bilkovic et al. 2005, King et al. 2005, Seitz et al. 2006, Bilkovic et al. 2006, Bilkovic & Roggero 2008), increases in invasive species, such as Phragmites australis (Chambers et al. 1999, King et al. 2007), and disturbance of sediment budgets sustaining adjacent properties. As an alternative to traditional armoring of shorelines, shoreline protection techniques incorporating natural elements from the system are increasingly …


Microbial Methane Production In Oxygenated Water Column Of An Oligotrophic Lake, Hans-Peter Grossart, Katharina Frindte, Claudia Dziallas, Werner Eckert, Kam W. Tang Dec 2011

Microbial Methane Production In Oxygenated Water Column Of An Oligotrophic Lake, Hans-Peter Grossart, Katharina Frindte, Claudia Dziallas, Werner Eckert, Kam W. Tang

VIMS Articles

The prevailing paradigm in aquatic science is that microbial methanogenesis happens primarily in anoxic environments. Here, we used multiple complementary approaches to show that microbial methane production could and did occur in the well-oxygenated water column of an oligotrophic lake (Lake Stechlin, Germany). Oversaturation of methane was repeatedly recorded in the well-oxygenated upper 10 m of the water column, and the methane maxima coincided with oxygen oversaturation at 6 m. Laboratory incubations of unamended epilimnetic lake water and inoculations of photoautotrophs with a lake-enrichment culture both led to methane production even in the presence of oxygen, and the production was …


A Geotechnical Evaluation Of Chesapeake Beach Shoal For Beach Quality Sand, Donna A. Milligan, C. Scott Hardaway Jr., Mary C. Cox, Christine A. Wilcox Dec 2011

A Geotechnical Evaluation Of Chesapeake Beach Shoal For Beach Quality Sand, Donna A. Milligan, C. Scott Hardaway Jr., Mary C. Cox, Christine A. Wilcox

Reports

Chesapeake Beach Shoal is located along the southern coast of Chesapeake Bay in Virginia Beach, Virginia (Figure 1-1). Chesapeake Beach, which is nearly adjacent, has a history of chronic beach erosion which threatens upland infrastructure. Beach nourishment occurs on Ocean Park Beach to the east from intermittent dredging of Lynnhaven Inlet (Figure 1-2), but the effects do not always translate westward to Chesapeake Beach. The general alongshore sand movement is east to west. The purpose of this project is to establish a reliable source of beach sand for Chesapeake Beach via the nearshore shoal. Many issues, including identifying the location …

Northampton County, Virginia Shoreline Inventory Report Methods And Guidelines, Marcia Berman, Harry Berquist, Sharon Killeen, Carl Hershner, Karinna Nunez, Karen Reay, Tamia Rudnicky, Daniel E. Schatt Nov 2011

Northampton County, Virginia Shoreline Inventory Report Methods And Guidelines, Marcia Berman, Harry Berquist, Sharon Killeen, Carl Hershner, Karinna Nunez, Karen Reay, Tamia Rudnicky, Daniel E. Schatt

Reports

The data inventory developed for the Shoreline Inventory is based on a three tiered shoreline assessment approach. In most cases this assessment characterizes conditions that can be observed from a small boat navigating along the shoreline. The three tiered shoreline assessment approach divides the shorezone into three regions:

1 ) the immediate riparian zone, evaluated for land use; 2 ) the bank, evaluated for height, stability, cover and natural protection; and 3 ) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes. Hand-held GPS units are used to log features observed in the field.

Shoreline Evolution: Richmond County, Virginia Rappahannock River Shorelines, Donna A. Milligan, Christine Wilcox, C. Scott Hardaway Jr. Sep 2011

Shoreline Evolution: Richmond County, Virginia Rappahannock River Shorelines, Donna A. Milligan, Christine Wilcox, C. Scott Hardaway Jr.

Reports

Richmond County is situated on the Northern Neck Peninsula in the eastern portion of Virginia (Figure 1). The Rappahannock River forms the southern boundary of this 192 square mile community. The County has 149 miles of shoreline on the Rappahannock River and Cat Point and Totuskey Creeks. Through time, the County’s shoreline has evolved, and determining the rates and patterns of shore change provides the basis to know how a particular coast has changed through time and how it might proceed in the future. Along Chesapeake Bay’s estuarine shores, winds, waves, tides and currents shape and modify coastlines by eroding, …


Evaluating Recruitment Of American Eel, Anguilla Rostrata, In The Potomac River (Spring 2011), Troy D. Tuckey, Mary C. Fabrizio Sep 2011

Evaluating Recruitment Of American Eel, Anguilla Rostrata, In The Potomac River (Spring 2011), Troy D. Tuckey, Mary C. Fabrizio

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan (FMP) for the American eel in November 1999. The FMP focuses on increasing coastal states’ efforts to collect American eel data through both fishery-dependent and fishery-independent studies. Consequently, member jurisdictions agreed to implement an annual survey for young-of-year (YOY) American eels. The survey is intended to “…characterize trends in annual recruitment of the YOY eels over time [to produce a] qualitative appraisal of the annual recruitment of American eel to the U.S. Atlantic Coast” (ASMFC 2000). The development of these surveys began in 2000 with full implementation …


Sea Level Rise: Local Fact Sheet For The Middle Peninsula, Virginia, William G. Reay, Sandra Y. Erdle Sep 2011

Sea Level Rise: Local Fact Sheet For The Middle Peninsula, Virginia, William G. Reay, Sandra Y. Erdle

Reports

A look at the geologic record of Chesapeake Bay shows a long and dynamic history - from the bolide (asteroid or comet) impact about 35 million years ago which formed the Chesapeake Bay impact crater, to the melting of glaciers beginning about 18,000 years ago, resulting in a continued rise of sea level and drowning of the Susquehanna River valley. Given that the rise in sea level has been occurring for thousands of years and is fundamental to the present formation of the Chesapeake Bay and our local tidal waters, why is there a recent heightened level of concern regarding …


Shoreline Evolution: Surry County, Virginia James River Shorelines, Donna A. Milligan, Christine A. Wilcox, C. Scott Hardaway Jr. Sep 2011

Shoreline Evolution: Surry County, Virginia James River Shorelines, Donna A. Milligan, Christine A. Wilcox, C. Scott Hardaway Jr.

Reports

Surry County is situated on the southern shore of the James River (Figure 1). The County has 168 miles of shoreline along the James River, Upper Chippokes Creek and Grays Creek. Through time, the County’s shoreline has evolved, and determining the rates and patterns of shore change provides the basis to know how a particular coast has changed through time and how it might proceed in the future . Along Chesapeake Bay’s estuarine shores, winds, waves, tides and currents shape and modify coastlines by eroding, transporting and depositing sediments.

The purpose of this report is to document how the shore …


Colonial Beach State Of The Beach Report: 2011, Donna A. Milligan, C. Scott Hardaway Jr., Christine Wilcox Sep 2011

Colonial Beach State Of The Beach Report: 2011, Donna A. Milligan, C. Scott Hardaway Jr., Christine Wilcox

Reports

The Town of Colonial Beach occupies a peninsula between the Potomac River and Monroe Bay. Approximately 2.5 miles of the shoreline is publicly-owned. Two areas on the Potomac River have been enhanced as recreational beaches for swimming and sunbathing. Central Beach is located just south of the Town Pier and is the main recreational beach. Castlewood Beach is south of Central Beach near the entrance to Monroe Bay. Mean tide range is 1.64 ft while the spring range 1.94 ft (NOAA,2011).

Specific shore change is addressed at Central Beach and Castlewood Beach through recent beach profiles. Beach profilestaken in January …
